mac80211: add support for tx to abort low priority scan requests
Use NL80211_SCAN_FLAG_LOW_PRIORITY flag in mac80211's scan state machine to prematurely terminate scan operations if outbound traffic collides. This is useful for marking background scans so they don't affect throughput. Signed-off-by: Sam Leffler <sleffler@chromium.org> Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> [set feature flag only if software scan is used] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
